WebDec 24, 2009 · Abstract. Background and Purpose— It has recently been proposed that fluid-attenuated inversion recovery (FLAIR) imaging may serve as a surrogate marker … WebSep 4, 2024 · Fluid attenuated Similarly in the brain, we often want to detect parenchymal edema without the glaring high signal from CSF. To do this we suppress CSF. This sequence is called FLAIR. Importantly, at first glance FLAIR images appear similar to T1 (CSF is dark). The best way to tell the two apart is to look at the grey-white matter.

WebJul 14, 2024 · Multiple sclerosis (MS) is an inflammatory, demyelinating autoimmune disease of the central nervous system (CNS). Its pathophysiological processes lead to focal lesions in the brain, which are detectable using MRI. 1 Standard MRI protocols comprise native and contrast-enhanced T 1-weighted imaging, proton fluid attenuated inversion … WebFluid-attenuated inversion recovery (FLAIR) is an inversion-recovery pulse sequence designed to nul-lify or greatly reduce the signal from CSF. It pro-vides heavily T2-weighted images without a very high signal or potential artifacts from CSF (1–6). Clinical applications of the FLAIR technique have been described (3–6), and its clinical utility
